This figure shows average absolute sea level change, which refers to the height of the ocean surface, regardless of whether nearby land is rising or falling. Satellite data are based solely on measured sea level, while the long-term tide gauge data include a small correction factor because the size and shape of the oceans are changing slowly ...
The global average sea level has risen about 25 centimetres (9.8 in) since 1880. [1] Sea surface height change from 1992 to 2019: Blue regions are where sea level has gone down, and orange/red regions are where sea level has risen (the visualization is based on satellite data). [2]
Mid- and late 21st-century (2046–2065 and 2081–2100 averages, respectively) projections of global warming and global mean sea level rise from the IPCC Fifth Assessment Report (IPCC AR5 WG1) are tabulated below. The projections are relative to temperatures and sea levels in the late 20th to early 21st centuries (1986–2005 average).
A chilling animation from Nasa shows how far the sea level has risen in the past 30 years. “As the planet warms and polar ice melts, our global average sea level is rising,” Nasa wrote ...
Baart et al. (2012) show that it is important to account for the effect of the 18.6-year lunar nodal cycle before acceleration in sea level rise should be concluded. [25] Based on tide gauge data, the rate of global average sea level rise during the 20th century lies in the range 0.8 to 3.3 mm/yr, with an average rate of 1.8 mm/yr. [26]
Image showing sea level change during the end of the last glacial period. Meltwater pulse 1A is indicated. Meltwater pulse 1A (MWP1a) is the name used by Quaternary geologists, paleoclimatologists, and oceanographers for a period of rapid post-glacial sea level rise, between 14,700 and 13,500 years ago, during which the global sea level rose between 16 meters (52 ft) and 25 meters (82 ft) in ...

Comparison of two sea level reconstructions during the last 500 Myr: Exxon curve and Hallam curve. The scale of change during the last glacial/interglacial transition is indicated with a black bar. The sea-level curve (also known as the eustatic curve) is the representation of the changes of the sea level relative to present day mean sea level ...
